In this new release I have created a Manual page with some nice formatting. And expanded on some of the options now providing more meaningful information. The man page can be seen by typing:
man ./script
In the future this would be added to the PATH so that it can be seen from any location the same with the actual script.
As for the script I have expanded the help section to provide the information given in the man page.
Also I have automated the retrieval of the pidora kernel that I was previously unable to do it because I had no idea how to construct the url that provided me with the source RPM.
Some other notes:
For the Pidora source RPM it only looks for packages in the f19-rpfr Tag when changing to f20-rpfr this line would need to be modified.
The -b option now will take 3.11 instead of 3.11.y, using 3.11.y will cause errors. It is better anyways to use 3.11 just simpler.
There is no error checking so if the information provided is not right it will not finish successfully.
Still no name for the script .... Poor nameless script.
Since the scripts where getting too long I am instead linking to a file.
Man page:
https://drive.google.com/file/d/0B2G5T2vxJmLrUEhhZ1BrQ1JYWDA/edit?usp=sharing
Script:
https://drive.google.com/file/d/0B2G5T2vxJmLrTjJzcTNDeENEeDA/edit?usp=sharing
And I am off to Ecuador, it was great working on this. I will continue working on it when I return.
I plan on adding some error checking, some other useful options and cleaning up the the code more.

Release 0.2.1
Various bugfixes
Added email option to report when a new kernel is building - could not test it because bell blocks port 25

In this release I added Options which will provide help with the -h option, -l will list the branches, -b will specify the branch and -k will specify which url to use to download the koji source rpm.

Release 0.1.5
- After seeing that wget was not actually getting the source how it was supposed to I made a few changes. So instead of using wget to retrieve commits and the kernel versions I am using git ls-remote it is way better.
- Date now is using the build date instead of the date of the commit
- Instead of looking for the rpmbuild folder in home which is the default directory I am retrieving the information from the %{_topdir} variable. This way if somebody has setup the rmpbuild directory to another location the script will still be able to function properly.

Release 0.1.1
I have modified my release 0.1 to send to koji the right source package, before it was looking for the wrong one. I could not test this because I had not setup the keys to access the koji system in seneca.
The lines modified are:
# Send Source Package to Koji
release=$( cat ~/rpmbuild/SPECS/raspberrypi-kernel.spec | grep Release | cut -d ' ' -f9 | cut -d '.' -f1)
srcrpm=$(echo "raspberrypi-kernel-3.11.6-"$release"."$commit_date"git"$short_commit".rpfr19.src.rpm")

koji -s 'http://japan.proximity.on.ca/kojihub' build f18-rpfr-updates-automated ~/rpmbuild/SRPMS/$srcrpm
When sent to koji I get the following error
ActionNotAllowed: policy violation (build_from_srpm)
Perhaps it is because I am not yet a user in the koji system or maybe because I am taking the file from SRPMS.
I have also started looking into getops for 0.2 and a few other tweaks for gathering the information and files needed.

After doing some spending some time with my code given that the presentation day was upon me, I managed to get the most of the code up and running with the exception of the last command koji that was not accepting my keys.

There it is my code. I got to say, I was a rusty with bash

Python Lab
Python lab:
Python from the little I have played with python it shares some similarities with java. I do appreciate the fact that it forces you indent your code and make it closer to be universal but I do miss starting and ending brackets. I also miss ending code statements with ; This means that I cannot put another line of code in the same line. Variables are also handled differently as you do not need to setup the type for them. This could maybe become a little bit confusing if not being careful because the variable could switch from int to string for example well if python permits that.
In general it is easy to start coding with python if there is a previous java/c experience. For the part Google is kind enough to help.
17 import random
18 import os
19 import sys
20
21 #Intro and tutorial
22 os.system('clear')
23 print ("#####################")
24 print ("#Rules of the game: #")
25 print ("#####################\n")
26 print ("Guess the right number from 1 to 100")
27 print ("The maximum number of tries is 15, good luck !!!\n")
28
29 try:
30 raw_input("press enter to continue...")
31 # Handle interrupts like ctrl+c
32 except KeyboardInterrupt:
33 print ("\nUntil next time quitter")
34 sys.exit()
35
36 # Initialize vars
37 guess = 0
38 numTries = 0
39 secret=random.randint(1,100)
40
41 # Loop until answer is found or number of tries gets to 15
42 while (secret != guess and numTries != 15):
43 # Catch exceptions
44 try:
45 guess = int(raw_input("\nEnter a guess: "))
46 if guess < secret:
47 numTries = numTries + 1
48 print "Too low! , Try #:", numTries
49 elif guess > secret:
50 numTries = numTries + 1
51 print "Too high! , Try #:", numTries
52 else:
53 numTries = numTries + 1
54 print "Correct!, Total number of tries:", numTries , "\n"
55 if numTries == 15:
56 print "\nMaximum number of tries reached, Good luck next time !!!\n"
57
58 # Handle characters other than int
59 except ValueError:
60 print ("Please enter integers only")
61
62 # Handle interrupts like ctrl+c
63 except KeyboardInterrupt:
64 print ("\nUntil next time quitter")
65 sys.exit()
Here is my code. I did go a little bit further while playing with python. It is was really enjoyable. Of course improvements could be made … perhaps … but that is beyond the scope of this lab.
I went ahead and did everything in one commit. It was short enough to keep track of everything going in the code and find the errors instantly.
